Popis: Evaluation of the reasons for discontinuation of therapy with Janus kinase inhibitors (JAKi) may provide a clue to their more effective use.Objective : to analyze the survival of tofacitinib (TOFA) therapy and the reasons for its discontinuation in rheumatoid arthritis (RA) in real clinical practice.Patients and methods. The study included 30 adult patients with RA hospitalized to the V.A. Nasonova Research Institute of Rheumatology from 2018 to 2020 for the biologic disease modifying antirheumatic drugs (bDMARDs) or JAKi treatment. Patients were followed up for 3 years or until treatment with TOFA was discontinued, whichever occurred first.Results and discussion. TOFA was prescribed as the first line therapy in 3 patients. In all these patients, the drug was discontinued for the following reasons: insufficient efficacy (IE) after 2 full years of treatment; adverse reaction (AR); administrative reasons (AdR), i.e. the inability to continue therapy due to the lack of drug supply at the place of residence. 11 patients received TOFA as the second line therapy, in 8 of them the treatment was interrupted: in 4 due to IE, in 3 due to AR (skin allergy) and in 1 due to AdR one year after its initiation. TOFA was prescribed as a third line therapy in 9 patients, in 2 of them the drug was discontinued due to IE and in 3 due to AR (allergic dermatitis in 2, dyspepsia in 1). Another 1 patient refused treatment due to a planned pregnancy. 6 patients received TOFA as the fourth line therapy, 5 of them (83.3%) continued to receive it for more than 3 years. In 1 patient, TOFA was discontinued after 1 month due to the dry cough and shortness of breath onset. In another 1 patient who was prescribed TOFA as the fifth line therapy, treatment was discontinued due to AR (recurrent Herpes zoster).Conclusion. As the results of the study show, no relationship was found between the incidence of AR or IE and clinical and demographic indicators, as well as the frequency of TOFA withdrawal and the line of therapy. At the same time, the shortest duration of retention on TOFA therapy was noted when it was prescribed as a first-line drug.
